-Following paragraphs documents how to take images with **RTS2**. It is assumed that you have everything installed, and **RTS2**, including CCD drivers, runs on your computer.
-The examples given there assumes that your camera name in **RTS2** system is **C0**. If you camera is called differently, please use its name.
-====== rts2-xfocusc ======
-//rts2-xfocusc// displays CCD image on XWindow scree. If you have XWindows installed (graphical desktop on Linux), and you are either physically setting in front of the machine with camera or you are using ssh with the machine, //rts2-xfocusc// is the quickest way how to check that CCD is working. To take 2 second exposures, you will type:
-<code bash>
-rts2-xfocusc -d C0 -e 2
-</code>
-See attached example of the output:
-<code bash>

-For more options (you can change binning, do sub-window images, takes darks,..) please consult //rts2-xfocusc -h//.
-====== rts2-focusd ======
-//rts2-focusd// is similar to rts2-xfocusc. The only difference is that it will not use XWindows display to display images. By default it will save images in current directory, using //<camera_name>_<yyyy><mm><dd>-<hh><mm><ss>-<msec>.fits// as file name. Please consult //rts2-focusc -h// for more details.
-====== rts2-scriptexec ======
-//rts2-scriptexec// can be used to execute **RTS2** scripts on camera. Scripts are complex, yet simple "programs" used to take exposure, set various variables, etc.. Please consult //man rts2.script// for more details about **RTS2** scripts.
-The following example will take 2 20 seconds exposure, then change telescope named T0 offsets by 2 degrees in both RA and DEC, will take 2 10 seconds exposures, change filter to 2nd filter, and will take 11 1 seconds exposures, followed by darks for 1, 10 and 20 seconds:
-<code bash>
-user@host:~# rts2-scriptexec -d C0 -s 'for 2 { E 20 } T0.WOFFS+=(2,2) for 2 { E 10 } filter=2 for 11 { E 1 } D 1 D 10 D 20'
-</code>
-The resulting images are saved as //<camera_name>_<yyyy><mm><dd>-<hh><mm><ss>-<msec>.fits// to the current directory. If you will try to modify script, please bear in mind that you need to put space around brackets - e.g. this:
-<code bash>
-user@host:~# rts2-scriptexec -d C0 -s 'for 2 {E 20}'
-</code>
-is wrong, while this:
-<code bash>
-user@host:~# rts2-scriptexec -d C0 -s 'for 2 { E 20 }'
-</code>
-is correct.
